Kimchi refrigerator

Kimchi refrigerator is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kimchi refrigerator rather than just read about it. In short: A kimchi refrigerator is a refrigerator designed specifically to meet the storage requirements of kimchi and facilitate different fermentation processes. The kimchi refrigerator aims to be colder, with more consistent temperature, more humidity, and less moving air than a conventional refrigerator, providing the ideal environment for fermentation of kimchi.

Key takeaways

Kimchi refrigerator belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kimchi refrigerator to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kimchi refrigerator from memory before moving on to harder problems.

Reference excerpt

A kimchi refrigerator is a refrigerator designed specifically to meet the storage requirements of kimchi and facilitate different fermentation processes. The kimchi refrigerator aims to be colder, with more consistent temperature, more humidity, and less moving air than a conventional refrigerator, providing the ideal environment for fermentation of kimchi. Some models may include features such as a UV sterilizer. In a consumer survey aimed at South Korean homemakers conducted by a top-ranking Korean media agency in 2004, the kimchi refrigerator was ranked first for most wanted household appliance.

History and design The start of the Kimchi refrigerator dates back to 1984. At that time, LG predecessor, GoldStar (금성사), first used the word 'Kimchi refrigerator' (김치 냉장고). The model name of the first kimchi refrigerator was 'GR-063', and according to the advertisement, the inside was made of stainless steel and the internal temperature could be set, but it is assumed that the direct cooling method was adopted. The volume of this product was 45 liters. After many years of comprehensive work on development to best suit kimchi fermentation and storage, WiniaMando (만도기계) launched the commercial brand DIMCHAE (딤채) into the mass market in December 1995. The model name was 'CFR-052E'.

As of November 2007, more than a dozen home appliance manufacturers, including Samsung and LG, were involved in commercial production of kimchi refrigerators. The top-loading or "lid-type" designs were introduced first. The initial design took up much space and heavy plastic kimchi containers had to be lifted to get to the bottom part. Some units are now designed instead with two deep drawers on the bottom, that are accessible from the outside. Top or bottom, the bins can be used to refrigerate anything from kimchi to fresh produce and meats. The door-drawer types (the "stand-type" in Korea) are gaining popularity because of their space-saving ergonomic design. A single door with a wine-bar type design at the top can be opened in full or partially at the wine-bar section to save energy. The top portion can be used as a freezer.

Worked examples

Example 1 — a first encounter with Kimchi refrigerator

Start with the simplest possible case. Write down what Kimchi refrigerator claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kimchi refrigerator before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kimchi refrigerator ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kimchi refrigerator

In research: Kimchi refrigerator appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kimchi refrigerator in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kimchi refrigerator is common in secondary-school and first-year university syllabi. It links to neighbouring topics Home appliances, Kimchi, Refrigerators, so understanding it makes those chapters shorter.
In everyday life: Look for Kimchi refrigerator outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
